- '1 Claim.

This invention relates to a sight feed control of water softeningsolution for the treatment of water in boilers, the general object ofthe invention being to provide means whereby an air pocket can becreated in a gauge glass so that the drops of solution passing throughthe glass can be observed.

This invention also consists in certain other features of constructionand in the combination l0 and arrangement of the several parts to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim. I

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure l is a diagrammatic view with parts in elevation'and parts insection of the invention.

Figure 2 is an enlarged sectional view through the gauge glass and aircharging chamber and the connections between the parts.

In this drawing the numeral I indicates the compound container providedwith the sight this chamber by means of the funnel 3 which is connectedwith the upper .end of the container by means of a plug valve 4. A pipeline 5 connects the upper end of the container with a pressure watersupply and this line contains a needle control valve 6. A vent valve 1is connected with the coupling 8 which connects the a line 5 with thecontainer l. A drain pipe 9 containing a drain valve l 0 is connectedwith the bottom of the container. A pipe line ll leads from the lowerportion of the container l to a coupling l2 and contains a valve l3 andsaid coupling is connected with the upper gauge glass fitting I4 whichhas an air vent needle valve I5 at its upper end. The lower fitting isshown at 16 and the glass at IT. A coupling l8 connects the lowerfitting IS with a tube H! the lower end u by a smallcopper tube 28 whichis of angle shape and extendspart way into the upper portion of theglass.

In using the invention the chemicals are placed through the funnel 3into the container l by opening the valve 4 and the container and allthe 5 lines are filled with water. The valve 7 is opened, while theparts are being filled with water to permit air to escape from thecontainer 1 Then valves 13 and 25 are closed and valves l5 and 23 areopened. This will drain water from the 7 gauge glass Hand the aircharging chamber 22. Then valves I5 and 23 are closed and valve 25completely opened. Then valve i3. is opened slowly and as water dropsfrom the tube 28 through glass I1 and enters the air chamber'ZE the airin the chamber will rise up in the gauge glass H to form an air pockettherein and then the device is ready for use. In using the device thevalves 6 and Ham opened and by properly controlling valve 6 the compoundor solution is fed by drops through the air in the glass l1 and passesto the boiler. The drops falling through the glass ll can be observedand thus. one can ascertain just how many drops per minute are passingto the boiler. 25 gauge 2 and the chemicals are introduced into It isthought from the foregoing description that the advantages and novelfeatures of the invention will be readily apparent. g c It is to beunderstood that changes may be made in the construction and in thecombina- 30 tion and arrangement of the several parts provided that suchchanges fall within the scope of the appended claim.

Having described the invention, what is claimed as new is:

Means for supplying a softening solution to a boiler comprising acontainer for receiving softening material, means for connecting thecontainer to a water supply, a sight gauge, a pipe line connecting thecontainer to the upper end of 40 the gauge for leading the water withthe material therein from the container to the gauge,

a valve in the pipeline for closing the supply of water to the gauge, avent valve in the top of the gauge for venting air therefrom, a chamberforming member, a, vertically arranged pipe line connecting the upperend of said chamber forming member with the bottom of the gauge, a pipeline connecting an intermediate part of thelastmentioned pipeline to theboiler, a valve in the last-mentioned pipe line for closingcommunication between the air chamber forming member and the boiler anda drain valve in the bottom of the chamber forming member.
